Foreword

This document (EN 13706-1:2002) has been prepared by Technical Committee CEN /TC 249 "Plastics", thesecretariat of which is held by IBN.

This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by May 2003, and conflicting national standards shall be withdrawn at the latest byMay 2003.

Part 1 of this European Standard, EN 13706, establishes a data-block system for the designation of profiles madeby the pultrusion process from fibre reinforced plastic composites using a format and coding system established bythe International Standards Organisation (ISO) which is common to most fibre reinforced thermoset andthermoplastic materials. The system is intended to be applied only to materials ready for use.

The designation system is based on the premise that pultruded profiles can be divided into generic families basedon the polymer matrix used, the nature of the reinforcement and the in-service performance required.

The system is intended for the designation of a particular profile (or a small group of similar profiles) within ageneric family.

It is not intended to specify by this system the chemical composition or the volumetric content of the materialsmaking up the profile but to designate the profile for identification purposes only. It is the responsibility of theproducer of the profile to provide the appropriate designation.

The data-block system is also the basis for the specification given in Parts 2 and 3 of this standard.

EN 13706 consists of the following parts, under the general title Reinforced plastics composites - Specifications forpultruded profiles.

Part 1 : Designation

Part 2 : Methods of test and general requirements

Part 3 : Specific requirements

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.

1 Scope

1.1 This Part 1 of EN 13706 establishes a data block system for the designation of pultruded profiles made fromfibre reinforced plastics composites.

1.2 The types of pultruded profiles are differentiated from each other by a classification system based oninformation about type of polymer matrix used, the reinforcement material, the type of reinforcement and theadditional in-service performance features (e.g. fire retardancy, UV stability).

1.3 This European Standard is applicable to pultruded profiles made from fibre reinforced plastics compositesonly. It applies to materials ready for use in the form of straight lengths of section, or in coils, for structuralapplications (see clause 3.3 EN 13706-2:2002).

This European Standard does not apply to the following types of pultruded profile :

profiles designed primarily for their electrical properties ;

profiles which are classified as non-structural, that is having properties below the minimum required to conformto the grade E17 (see Table 1 of clause 4.4, EN 13706-3:2002).

1.4 This Part 1 of EN 13706 does not provide engineering data, performance data or data on service conditionswhich can be required to specify a profile for a particular application. If such additional properties are required,when ever possible, they shall be determined in accordance with the test methods specified in Part 2 of EN 13706.

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).

3 Terms and definitions

For the purposes of this European Standard, the terms and definitions given in EN ISO 472:2001 apply. Additionalterms and definitions are defined in clause 3 of EN 13706-2:2002.

4 Designation System

4.1 General

This designation system for pultruded profiles is based on the standardised pattern given below. It is applicable tospecifications described in Part 3 of EN 13706.

Designation

Identity block

EuropeanStandard

Individual block itemDescription block

(optional)

Number block Datablock 1

Datablock 2

Datablock 3

Datablock 4

Datablock 5

For unambiguous coding, the individual-item block is subdivided into a maximum of 5 data blocks comprising thefollowing information :

the description block shall be separated from the standard number block by a comma ;

spaces shall be inserted between blocks ;

the first character in the first individual item block shall be a dash ;

individual item blocks shall be separated from each other by a comma ;

if a data block is not used, this shall be indicated by two commas (,,).

NOTE This standardised pattern is a modification of the frame text given in ISO 1043-2, adapted to the designation ofthese reinforced products.

In this standard the Description block shall use the term “Pultrusion”.

4.2 Data block 1

In this data block, the profile shape is represented by a single code letter in position 1 and in position 2 thereinforcement material is represented by a single code letter for each type of reinforcement employed with theorder of the letters determined by their relative fibre volume content in the profile. In position 3, any additionalprocess used in the profile is given by a single code letter. The code letters used are given in Table 1.

4.3 Data block 2

In this data block, the resin system employed is represented by a single code letter in position 1.

The code letters used are given in Table 2.

For the purposes of this designation the code letter I includes Isophthalic and Terephthalic resin and the codeletter O includes Orthophthalic and Tetrahydrophthalic based resin systems.

Code letter Polymer Type

O Orthophthalic polyester

I Isophthalic polyester

V Vinyl ester

E Epoxy

P Phenolic

A Acrylic

D DCPD (dicyclopentadiene) resins

T Thermoplastic

Z Other

In position 2, specific non-structural properties required to meet the general service conditions for which the profileis designed shall be designated by an identification letter in accordance with Table 3. More than one of theseproperties may be combined within an individual pultruded section. This is shown by including the designatory letterfor each property without a space between them. In this case the letters should be written in the order given inTable 3.

Table 3 — Code letters in Data Block 2 for the specific property of the resin

Code Letter Property

F Fire retardant

U UV stabilised

Z Other

These properties may be achieved by the addition of additives to the resin formulation. Different additives may beused to achieve similar properties in the profile. The choice of additives should not be seen in isolation becausethey may affect other properties of the profile. This designation does not differentiate between different additivesneither does it quantify the level of performance. The minimum properties given in Part 3 of EN 13706 shall bemaintained in the presence of these resin modifications.

4.4 Data block 3

In this data block the code number for the grade of the profile, as listed in EN 13706-3:2002, Specific Requirements(see Table 1 of clause 4.4), shall be given.

NOTE The code number relates directly to the Effective Flexural Modulus of the full section profile determined inaccordance with the method given in clause 6 of EN 13706-2:2002. Two grades, E17 or E23, are currently defined.
